I thought it was insightful. Fundamentally, “move fast and break things” means you’re not going to be afraid to do something just because you haven’t thought through all the repercussions yet. Personally I find it easy to see how to, as an engineer...ignore hunches that there might be a security hole or a privacy hole in the interest of pushing things forward. “Move fast and break things” implies that you’ll get something working out the door and you’ll come back and fix it later. When you always move to the next thing, you never really come back and fix all the things you broke.
